The Controller Daemon, SQDaemon plays a key role in the authentication process by being the first point of contact for any agent requesting communication with any other agent in both single and multi-platform environments. See the Secure Communications Guide for more details regarding the Controller Daemon's role in security. Controller Daemons are accessed via a TCP/IP interface to an assigned Port on the platform where they are running. Their symbolic name is often synonymous with a specific Host (platform or Environment on which they are running.
The primary difference between an Engine Controller Daemon and a Daemon on Capture platforms is that the Authorized Key File of the Engine Controller Daemon need only contain the Public keys of SQDmon utility users on both the local and remote platforms.
Setup and configuration of the Engine Controller Daemon, SQDaemon, includes:
